President Trump’s administration has mandated that federal funds used to help human trafficking victims clear their criminal records, often accrued while forced into prostitution or sex slavery, no longer be spent for that purpose.

Barr this week asking why his department made changes that “fly in the face of the spirit and plain language” of laws passed to help trafficking victims.
